Intensity and State Estimation in Quantum Cryptography
... The polarization rotation protocols are based on fundamental cryptographic primitives [10]. The protocol called iAQC [5] is a variant of three-stage in which Alice and Bob track the intensity of the laser beam at each stage making it possible to detect the intruder. But the drawback of iAQC lies in ...

Dynamical quantum-electrodynamics embedding: Combining time
... The specific dynamical embedding proposed here combines a time-dependent quantum mechanical propagation (in practice TDDFT) with NF. The embedding is very simple since in NF the dynamics is non-retarded and is determined only by a longitudinal electric field, due to an overall electric potential, ju ...

Nobel Prize in Physics 2016 Flatland and Topology
... Since a topological invariant is an integer, it cannot change slowly if some small changes are made in the system The only way for a topological invariant to change is to become ill-defined at some point For example, if a closed curve in a plane is gradually deformed, its winding number can only cha ...

... neurotransmitter molecules. That is how a “mental order” may be translated into a “physiological action”. Our equation for quantum collapse, tailored to the MT system, predicts that it takes 10,000 neurons O(1 sec) to dynamically collapse, in other words to process and imprint information. Different ...

... In this chapter we want to couple electrons and photons with each other by an appropriate interaction and study the resulting interacting field theory, the famous quantum electrodynamics (QED). Since the coupling should not change the two physical degrees of freedom described by the four-component p ...
